Magnetic Domain Model Kit for Visual Magnetization Demo, Physics Classroom Teaching Tool
Product description
This transparent cuboid model demonstrates magnetization and demagnetization by simulating magnetic molecular structure. It makes magnetic alignment visible and repeatable, so students and instructors can observe how magnetic ordering forms and how disorder leads to loss of net magnetism.
Key benefits
Visual and handson demonstration of magnetization and demagnetization, ideal for classroom and laboratory use.
Simple operation lets users show how an external magnetic field aligns magnetic elements and how agitation or irregular fields break that alignment.
Durable, fully transparent housing gives clear 360 degree visibility of internal behavior for group demonstrations and individual study.
How it works
The model is a cuboid, fully transparent plastic box with an array of 24 steel posts mounted on the bottom in four rows of six.
Twentyfour small magnetic plates sit on the steel posts; each small magnet can rotate on its support.
Moving a bar magnet in one direction over the model causes the small magnetic plates to align uniformly; the aligned arrangement remains after the bar magnet is removed, demonstrating magnetization.
Moving hoof magnets irregularly above the flat glass surface or gently vibrating the box causes the small magnetic plates to fall into disorder; their magnetic vectors cancel and the model shows demagnetization.
Features and specifications
Shape and enclosure: Cuboid shape, fully transparent plastic box for unobstructed observation.
Internal structure: 24 steel posts arranged in four rows of six at the bottom of the box.
Magnetic elements: 24 small magnetic plates mounted on the steel posts; each small magnet is to rotate.
Demonstrable behaviors: Clear simulation of magnetization when exposed to a uniform moving bar magnet and demagnetization when exposed to irregular magnet motion or vibration.
Operation: Use a bar magnet to induce ordered alignment; use hoof magnets or gentle vibration to induce disorder.
Practical applications
Physics and education: Demonstrate domain alignment, magnetization, and demagnetization in school and university physics classes.
Laboratory teaching: Use in lab exercises to compare uniform versus irregular magnetic fields and to illustrate concepts such as magnetic domains and net magnetic moment.
Science outreach and exhibits: Portable visual aid for public demonstrations and museum exhibits to help nontechnical audiences grasp magnetic behavior.
Why choose this model
Directly shows microscopic magnetic ordering with a durable, easytohandle apparatus.
No complex setup required; demonstrations are repeatable and immediately observable.
Transparent enclosure and organized internal layout make it suitable for both closeup laboratory use and largergroup demonstrations.
Included functions
Magnetization demonstration with a bar magnet moved in one direction.
Demagnetization demonstration using hoof magnets moved irregularly above the surface or by vibrating the box.
Care and use notes
Handle magnets and the plastic box with care to avoid strong impacts.
Place on a flat surface or a clear sheet of glass for stable demonstrations.
Use magnets externally; do not open the sealed box to alter internal components.
This model provides a simple, reliable way to visualize and teach the processes of magnetization and demagnetization through controlled, repeatable demonstrations.
